Mono-Green Eldrazi leans hard on Eldrazi Temple and Ugin's Labyrinth for extra colorless mana to cheat out Emrakul, the Promised End and Ulamog, the Ceaseless Hunger, so Damping Sphere is a premier answer that strips that bonus mana and taxes their multi-spell Green Sun's Zenith/Malevolent Rumble turns. Consign to Memory counters Kozilek's Command outright since it's a colorless instant, and Spell Snare picks off two-mana spells like Fanatic of Rhonas or Malevolent Rumble. Haywire Mite can answer Chalice of the Void or Trinisphere if they bring in artifacts of their own. Trim fetches and surveil-lands since games go long and you want maximum disruption density rather than early tempo lands.

Boros Energy floods the board with cheap creatures (Ocelot Pride tokens, Ragavan, Voice of Victory's Warrior tokens) backed by Goblin Bombardment, so Wrath of the Skies comes in as a sweeper to reset a board you can't out-block. The extra Teferi, Time Raveler lets you hold up sorcery-speed answers safely while stopping instant-speed disruption like Thraben Charm on your turn. Rest in Peace hoses their own graveyard recursion by exiling cards before they hit the graveyard. Trim slow, situational picks like Meticulous Archive's tempo loss and narrow removal for the extra impact cards.

Izzet Prowess wants to dump its hand into a wide, cheap board (Dragon's Rage Channeler, Monastery Swiftspear, Slickshot Show-Off) and pump it with burn, so Wrath of the Skies is a clean sweeper that resets the board even against a hand full of one-mana threats. Spell Snare answers Cori-Steel Cutter and Slickshot Show-Off at two mana, while Consign to Memory's extra copies help counter colorless spells like Mishra's Bauble (the card itself as a spell, not its activated ability, is what gets countered) and opposing triggered abilities. Since their removal (Lightning Bolt, Lava Dart, Unholy Heat) is aimed at your creatures rather than your board wipes, this is a favorable spot to overload on sweeper effects. Cut slow single-target removal and a surveil-land for the extra reach.
